Floating head heat exchanger
Floating head heat exchanger tube plate at one end is fixed, rigid connection with the shell, the other end of the tube sheet is active, the end of the floating head heat exchanger tube plate is fixed, rigid connection with the shell, the other end of the tube plate is active between the shell and is not connected, as shown. Activities referred to as floating head tube sheet side, between the floating head is not connected to the concrete structure.
Floating head heat exchanger tubes can be withdrawn from the shell, so the tubewall for easy cleaning, tube bundle in shell in free expansion, so no thermal stress; but the complex structure, high cost, floating head office will result in two if Mifengbuyankinds of fluid mixed and difficult to detect. Floating head heat exchanger for a largertemperature difference between hot and cold fluids, dielectric constant need to be cleaned easily scaling the occasion. Used in various types of chemical production inshell and tube heat exchanger in the floating head up.
